Abstract: PROBLEM TO BE SOLVED: To increase variations of presentations without increasing a control load.SOLUTION: A main control CPU determines a variation pattern distribution table on the basis of a special symbol (identifier), and selects one of variation patterns from the variation pattern distribution table. Also, a plurality of special symbols (big win symbols) for specifying same big wins (a 5R probability variation big win B and a 5R probability variation big win C) is set, and a variation pattern distribution table is set for each special symbol. Therefore, the variation pattern distribution table can be specified by only determining a special symbol.
